Terminal equipment of time division-long term evolution (TD-LTE) emergency voice communication system

Abstract

The invention provides terminal equipment of a time division-long term evolution (TD-LTE) emergency voice communication system. The terminal equipment comprises a display control module, a TD-LTE transmission module, a voice module, a battery management module and a Big Dipper positioning module. The display control module processes, displays and controls voice and information interaction. The TD-LTE transmission module is connected with a monitoring and command center through a base station and a TD-LTE core network and performs internet protocol (IP) data communication. The Big Dipper positioning module is used for acquiring position information of the emergency voice communication system. The battery management module is used for providing power for the whole emergency voice communication system. The terminal equipment is based on a TD-LTE technology, has the characteristics of high rate, small time delay, good stability, simple operation and so on, and is suitable for rapidly transmitting reliable information for occasions like emergency rescue in emergencies, rescue and relief work, law enforcement of public security and so on in real time.

Description

technical field [0001] The invention relates to the technical field of wireless communication, and relates to a mobile communication terminal, in particular to a TD-LTE emergency communication system voice terminal equipment. Background technique [0002] In recent years, natural disasters, large-scale accidents, and public safety emergencies have occurred frequently, and emergency communication has become more and more important. In order to effectively command and dispatch, efficient on-site rescue and disposal, it is necessary to maintain real-time communication between the scene of the incident and the remote command center as well as the communication between the on-site personnel. Due to the complex and changeable environment of many incidents, it is difficult to use large-scale communication equipment, and more portable and reliable communication devices are needed for all-weather real-time communication. [0003] TD-LTE is a 4G standard developed by my country. With...
